Fw: can anybody help me - Pike-devel

30 Sep 2002


      so about image processing.
 sure I know that tgere is gxml but I dont have any samples or documentation
 how to edit some image and show it to user in web browser
there is some stuff I done by my self. this is maximum I can figure out
 in attachments you can see what I have done
 and there it is on web
 http://katalogs.core.lv/demo
peace of script. this section will build thumbnails from
 images in selected folder (on the web page you can see)
buff =
 Stdio.read_bytes("/box1/demo/"+id->variables->cat+"/"+id->variables->img);
   if (buff != 0 )
    {
object OurImage;
    OurImage = Image.JPEG.decode(buff);
     float xsize = (float) OurImage->xsize();
     float ysize = (float) OurImage->ysize();
float scale = 1.0;
     if (xsize > ysize) scale = ((float) 90)/xsize;
     else scale = ((float) 70)/ysize;
OurImage = OurImage->scale(scale);
     reply = Image.JPEG.encode(OurImage);
   array dir = get_dir("/box1/boss/demothumbs/"+id->variables->cat+"/");
    if (arrayp(dir)==0)
    {
     mkdir("/box1/boss/demothumbs/"+id->variables->cat+"/");
    }
    open_res = me->open("/box1/boss/demothumbs/"+id->variables->cat+"/" +
 id->variables->img,"cw");
    if (open_res == 1)
     me->write(reply);
    me->close();
    }
   else
    {
    open_res = me->open("/box2/fotodata/default/not_found.gif","r");
    reply = me->read();
    me->close();
    }
so there I made decode and encode jpg image
 and image resizing
so I wan to add there more image pike options
 like sharpen blur colorize lighten darken and more (or also draw some ither
 image transparent gif as logo )
 of course these options will be seperated by if conditions
it would give ability to proccess images on the fly and add some effects
on the web site you can see some samples I have done with cimg and gtext
 but I dont like this
 pike is faster and more options more
actualy I wan to create a web site where users can
 pick some image put some nice text on it some masks effects
 borders . in one word . add on image some stilistic stuff
 and in result will get very nice personalised postcard
..
 also it is important for web site creation
 dinamicaly draw texts effects and more on images
